The current error exit path if ir_raw_encode_scancode fails is via the
label out_kfree which kfree's an uninitialized pointer txbuf. Fix this
by exiting via a new exit path that does not kfree txbuf. Also exit
via this new exit path for a failed allocation of txbuf to avoid a
redundant kfree on a NULL pointer (to save a bunch of CPU cycles).

patch extracts that data, adding more clock synchronisation information,
on both bulk and isochronous endpoints and makes it available to the user
space on a separate video node, using the V4L2_CAP_META_CAPTURE capability
and the V4L2_BUF_TYPE_META_CAPTURE buffer queue type. By default, only the
V4L2_META_FMT_UVC pixel format is available from those nodes. However,
cameras can be added to the device ID table to additionally specify their
own metadata format, in which case that format will also become available
from the metadata node.

there are still buffers waiting to be filled. However, it doesn't

Currently, there's a logic with checks if *count is non-zero,

That's flawed when the device is initialized, or after the
queues are freed, as it does, unnecessary calls to
__vb2_queue_cancel() and __vb2_queue_free().
That can be avoided by making sure that q->memory is set to
VB2_MEMORY_UNKNOWN at vb2_core_queue_init(), and adding such

Pull irq fixes from Thomas Gleixner:
"A rather large update after the kaisered maintainer finally found time
to handle regression reports.
- The larger part addresses a regression caused by the x86 vector
management rework.
The reservation based model does not work reliably for MSI
interrupts, if they cannot be masked (yes, yet another hw
engineering trainwreck). The reason is that the reservation mode
assigns a dummy vector when the interrupt is allocated and switches
to a real vector when the interrupt is requested.
If the MSI entry cannot be masked then the initialization might
raise an interrupt before the interrupt is requested, which ends up
as spurious interrupt and causes device malfunction and worse. The
fix is to exclude MSI interrupts which do not support masking from
reservation mode and assign a real vector right away.
- Extend the extra lockdep class setup for nested interrupts with a
class for the recently added irq_desc::request_mutex so lockdep can
differeniate and does not emit false positive warnings.
- A ratelimit guard for the bad irq printout so in case a bad irq
comes back immediately the system does not drown in dmesg spam"
